Bad batches of synthetic marijuana “K2” is the debt of dozens of overdoses, and even a few deaths in the whole country. What exactly is in this “fake weed” and how dangerous is it?

Connecticut authorities Friday revealed that a man was arrested in connection with the investigation of some of the dozens of synthetic pot overdoses that have occurred in the state this week.

John Parker, 53, was taken into custody Wednesday, and was discovered with more than 30 bags of K2, the synthetic marijuana linked to more than 100 overdose, police said.

Parker was hit with drug-related charges after authorities found him with the K2, commander Anthony Campbell said.

The area around the New Haven Green in the neighborhood of Yale, where many of the overdoses occurred, starting on Wednesday. Several people who were affected by the drug identified Parker as someone who would have been in the area, Campbell said.

Cots were Thursday as a makeshift treatment center on the New Haven Green for the process of drug overdoses.

Some of those who suffer from an overdose and fell unconscious, while others suffer from nausea and vomiting, officials said. Some individuals also reportedly overdosed multiple times.

No deaths have been reported.

Parker was held on $225,000 bail. A public prosecutor told The Associated Press there was no evidence linking drugs Parker had the ODs.

His arrest is the third in the research. Felix Melendez, 37, and an unidentified individual were separately taken into custody, Campbell said. He added that researchers are still trying to determine whether or not they are connected to an overdose.

The police warned that the fears cannot guarantee that all of the bad K2 has found.

“We want people to be warned that what they have can be very dangerous and they should not use it,” Campbell said.

Synthetic marijuana typical consists of plant material sprayed with chemicals or other substances sold in small, colorful packages.
